Noritsu 3301 6106 G Laser error, Digital Noise In Tests


Digimati

Recommended Posts

Some mornings, when I start a mini-lab when I do Daily Setup i get an error message 6106-0001 and there is digital noise in test. I have done a reboot, turned off the power, and since then I have received a test without digital noise. Could I replace the green AOM with a new one, or does it not make sense and need to be replaced a green laser?

I changed, as recommended, the G laser. I had a type A laser in my device before, but since it wasn't available, I installed a type B laser with a new driver. But after that, there was a problem with the temperature of the R laser. The display continues to display the message Laser temperature R laser adjusted and it does not disappear?
What do you advise me to do?

Check all the connectors are plugged in.

Have a look at this post

Voltage:
 

Voltage on LASER I/O PCB connector J/P1540 between pin 1 and pin 2 = 4,95V

Between ground and LASER I/O PCB connector J/P1532 pin 7 = 1V

Between ground and J/P1532 pin 8 = -0,29V

 

between ground and J/P1535 pin 1 and 3 = 5V

between ground and J/P1541 pin 1 , 2 and 3 = 24V

between ground and J/P1550 pin 1 = 12V

between ground and J/P1550 pin 4 = -12V

R laser temperature is too low. You see 21 degree ( instead of 28 degrees ) . 

Are you sure about multimeter connection? On sensor output ( J/P1532 pin 8 ) can't be negative voltage.
Black multimeter wire should be connected to ground and red - to connector pin.
Between ground and J/P1532 pin 7 should be 1V( reference voltage )
Between ground and J/P1532 pin 8 voltage depends on R laser temperature, but it should be positive.
Try power off minilab and reconnect J/P1532 .

Disconnect J/P1540 . With multimeter on connector check resistance. Resistance need to check on connector ( not on board ) . To this connector is connected R laser TEC.
When TEC connected ( see resistance ) and you have voltage then R laser should heat, or cool. 
When on J/P1540 pin 1 is 0V and on pin 2 is 5V then R laser should heat up.
When on J/P1540 pin 1 is 5V and on pin 2 is 0V then R laser should cool down.
